Biotic Factor Plant: Free-floating algae o Red algae ( Rhodophyta) -- Porphyra (from which edible nori is made), dulse, Ceramium and maerl o Green algae (Chlorophyta) --thongweed, sea lettuce (Ulva) o Brown algae (Phaeophyta) -- like fast-growing kelp, Sargassum, Turbinaria, Dictyota, and wrack
Phytoplankton -- tiny, one-celled photosynthetic plankton like diatoms, dinoflagellates, and coccolithophorids
Flowering plants (angiosperms)
Submerged: Seagrasses -- flowering plants like eelgrass and thalassia
Not Entirely Submerged: Mangroves -- trees that root in the shallow seafloor but grow above water

Orca
Abiotic Factor The upper most part of the ocean is called the sunlit or eupotic zone, and averages at about 660 feet. Temperature ranges from 27 to 104 degrees F. Many plants grow here because it has enough light to support photosynthesis. About 90% of gaseous oxygen comes from the ocean. Most of this oxygen comes from phytoplankton (the first link of the food chain in the ocean). Because of the food (phytoplankton/autotrophs), most fish live in this zone
THREAT
The threat of the bluefin tuna is extinction due to overfishing. Japan started overfishing in the late 1960s. The demand for them went up extremely high because of taste and low supply. People started fishing them much faster than normal because of high selling prices (one sold for more 150,000 U.S. dollars.) If this keeps happening, the bluefin tuna could soon be extinct. L
Conservation plan
Make breeding farms for Blue fin tuna and release all of them. Also make laws in Japan that will stop the overfishing of the Bluefin tuna and kill all of those who oppose the rule, strict laws shall be made to help the survival of the Bluefin tuna.
Importance
The Bluefin tuna is going extinct because of the Overfishing. If the Bluefin Tuna is to go extinct it will disrupt the food web of the ocean and may end life as we know it. The Bluefin Tuna is crucial for the Med Ocean food chain, it is one of the top predators.
